Glue manufacturer case sharing, what glue is used for magnet bonding and acrylic three proof paint 6441 model product introduction
What kind of adhesive should be used for bonding magnets? In our daily lives and work, the use of magnets has become indispensable. So, what is the best adhesive to use for bonding magnets? First, let’s discuss what magnets are.
Magnets are made up of atoms of iron, cobalt, nickel, and other elements, which have a unique internal atomic structure that inherently possesses a magnetic moment. Magnets can generate a magnetic field, enabling them to attract ferromagnetic materials such as iron, nickel, and cobalt. Over centuries of development, magnets have become powerful materials essential in our lives. By synthesizing different alloys, we can achieve the same effects as natural magnets while enhancing magnetic strength.
Here are two case studies on magnet bonding that may be helpful:
